The invention provides an electronic device with an infrared touch function, which comprises a display unit, a main processing unit and an infrared touch device. The infrared touch device comprises an infrared transmitting tube and a plurality of infrared receiving tubes; the plurality of infrared receiving tubes are arranged on a circuit board for receiving infrared signals transmitted by the infrared transmitting tube and forming a plurality of infrared connecting lines together with the infrared transmitting tube; and the plurality of infrared connecting lines form a non-matrix structure. The infrared touch device judges and sends messages of the interrupted infrared connecting lines to the main processing unit; and the main processing unit defines a message that each infrared connecting line corresponds to a menu icon and acquires the menu icon which is touched by a user according to the interrupted infrared connecting lines so as to execute an instruction corresponding to the touched menu icon. The invention also discloses an infrared touch control method.
